Abstract: A  wavelength stabilization apparatus and method for a superfluorescent source comprising a SFS (superfluorescent source) comprising a fiber with a core doped with lazing material.  The SFS source produces SFS light with an SFS wavelength when pumped with pump light from a pump light source having a pump light wavelength.  An output controller responds to a sample of the SFS light and operates to maximize the power of the sample of SFS light by automatically adjusting the pump light wavelength.  The output controller also has a pump power controller responsive to a sample of the pump light from the pump light source for stabilizing the output power of the sample of the pump light with respect to a predetermined reference output power level.

Title: Probe, kit, and method of amplification for increasing the sensitivity of nucleic acid hybridization assays
Inventor: PANDIAN SITHIAN
IPC: G01N33/58
Filed: 1994-06-28
Granted: 2010-12-14
Abstract: The present invention provides a method for simplifying and significantly enhancing the sensitivity of nucleic acid hybridization assays. A method is described whereby a single-stranded primary nucleic acid sequence that includes a region of sequences complementary to a single-stranded target nucleic acid sequence is hybridized to the target molecule. Stability of the double-stranded complex thereby formed can be enhanced by using RNA as the probe if DNA is the target or DNA as the probe if RNA is the target. The probe-target complex is subsequently immunocaptured for detection. After washing away- extraneous material, a secondary nucleic acid sequence containing many repeating sequence units is hybridized to the probe component of the immobilized probe-target complex. Detection occurs following hybridization of many labelled nucleic acid sequence probes to each of the repeating sequence units of a nucleic acid amplification probe. Thus, attachment of multiple labelling probes to an amplification probe that is hybridized to an immobilized probe-target complex, provides a simplified method for amplifying the detection signal and therefore the sensitivity of nucleic acid hybridization assays.

Abstract: A radiotelephone, used in a satellite radiotelephone system, has an antenna (12) with a hemispherical gain pattern (14). Since a satellite (18) can be anywhere in the sky the antenna gain pattern (14) needs to be aligned with the hemisphere above the user. This is accomplished with an antenna positioning apparatus, comprising the antenna (12) having a wedge shaped mating surface (42) affixed to an attaching surface (36) by a pin (38) and socket (44).  The attaching surface (36) slopes downward from a plane (24) defined by a front face (26) of the radiotelephone (10). The combination of the wedge shaped mating surface (42) and the downward sloping attaching surface (36) positions the antenna (12) at an angle ? from the plane (24) when the antenna is in the active position. As a result the antenna (12) is vertically oriented when held by the user during normal use.

Title: Method and apparatus for automatic gain control and dc offset cancellation in quadrature receiver
Inventor: WILSON NATHANIEL B
IPC: H03G3/30
Filed: 1995-04-28
Granted: 2003-01-28
Abstract: An automatic gain control (AGC) and D.C. offset correction method and apparatus for controlling signal power of a received RF signal within a dual mode quadrature receiver is disclosed herein. The AGC apparatus includes an adjustable gain amplifier (18). A quadrature downconverter (20) coupled to the amplifier (18) serves to translate the frequency of the output signal to a baseband frequency which is offset by a predetermined margin from D.C. Two high gain active lowpass filters (76 and 78) provide out-of-band signal rejection for the baseband signals. A D.C. feedthrough suppression loop supresses D.C. offsets produced by a downconverter (20) and the lowpass filters (76 and 78). The AGC apparatus also generates a received power signal based on the power of the output signal. A saturating integrator compares the received power signal to a reference signal and produces the gain control signal by integrating or by refraining from integration based on values of the reference, received power signal, and gain control signals.

Title: Method for automatic maintenance of a local number portability database
Inventor: DUNN JAMES PATRICK
IPC: H04Q3/00
Filed: 1996-04-23
Granted: 2000-04-18
Abstract: A method for automatically updating a central LNP database shared among a plurality of central office switches is instigated when a message from a provisioning system to add a directory number is received by a central office switch. In response to the message, a first central office switch accesses the central LNP database by sending a query message which contains the directory number to be added and routing data specific to the central office switch. Responsive to the query message, the LNP  database searches for the directory number received from the first central office switch. If the directory number is found, the database queries a second central office switch to determine if the directory number is in use. If the number is in use, the central LNP database returns a failure message to the first central office switch. If the directory number is not found in the central LNP database or if the directory number is not being used by the second central office switch, the directory number and routing data received from the first central office switch and a transaction entry are added to a table corresponding to the first central office switch in the database.
